Removing and installing dust and pollen filter
Removing and installing dust and pollen filter
  Note
t  Replacement interval for dust and pollen filter → Maintenance tables
t  There are different versions of the dust and pollen filter (without and with activated charcoal filter element). Vehicles with an air conditioner of the „Deluxe“ type are currently fitted with a dust and pollen filter with an activated charcoal filter element, whereas vehicles with an air conditioner of the „Basic“ type currently have a dust and pollen filter with no activated charcoal element → Electronic parts catalogue.
t  Clean the area around the dust and pollen filter in the slot for the air conditioning unit before fitting a new filter.
t  It may be necessary to remove the driving instructor's pedals on driving school vehicles (depending on version, the driving instructor's pedals may be provided with service disconnection points) → Heed fitting instructions for driving school equipment.
t  In Model Year 2012, a modified dust and pollen filter with ACF element is to be gradually introduced on vehicles with an air conditioner of the „Deluxe“ type. This filter with an enhanced fine dust separation rate has roughly the same air resistance values as the filter fitted prior to conversion and can thus also be installed on vehicles manufactured prior to conversion → Electronic parts catalogue.
t  If so requested by the customer, vehicles with an air conditioner of the „Basic“ type fitted at the factory with a dust and pollen filter with no ACF element can also be provided with a dust and pollen filter with ACF element → Electronic parts catalogue.
